Historical statistics for July 2025 to June 2026, not live status. For today’s UA 2407, check with United Airlines.
UA 2407 lands a B+, 3 points better than the national rate of 77.6%. About one flight in five arrives 15 minutes late or worse, and those flights are late by about an hour on average. That is a workable record, not a spotless one. That rests on 308 flights, with a median arrival 8 minutes early.

These figures cover 308 flights between July 2025 and June 2026. The median arrival is 8 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.
Schedule
When UA 2407 flies
UA 2407 flies RDU to IAH without a single fixed slot. Its most common scheduled departure was 16:44, used on 49 of 308 flights, with 17:00 (41 flights) and 16:53 (35 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 16:44 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and UA 2407 runs 8 points better at 80.1%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year
UA 2407 quarter by quarter
UA 2407 did not run the same all year. Its best quarter was Jan–Mar 2026 at 89.2% on time and its weakest Jul–Sep 2025 at 64.1%, a swing of 25 points on roughly 77 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

- Oct–Dec 202591 flights81.3%
- Jan–Mar 202684 flights89.2%

Scale runs 55% to 95%. Rows with fewer than 30 flights show a dash.
By weekday, UA 2407 ranged from 73.9% on Thursday to 85.4% on Monday. With about 44 flights behind each day, a spread of 12 points is inside normal variation, so the day you fly is not worth changing for this flight.
Delay causes
Why UA 2407 runs late
One category carries most of the weight here. National Airspace System accounts for 54% of the 4,017 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.
- 54%National Airspace System
- 30%Late-arriving aircraft
- 13%Carrier
- 3%Extreme weather
54% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 2,187 minutes out of 4,017, against a national NAS share of 21%. The split is drawn from 4,017 delay minutes reported on UA 2407.
Cancellations are rare at 0.32%, below the national 1.81% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.
Connections and routes
What a delay on this flight costs
7.5% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about an hour, which a normal layover absorbs.
The 1,042 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.
The same number turns up on three other city pairs in the data, including IAH to ABQ (218), IND to DEN (9) and IAH to SAN (6), but none flew often enough under UA 2407 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to RDU to IAH only.
One caution: this is a thin sample. 308 flights over twelve months is enough to clear this site's floor but not enough to pin the rate down tightly, and a single bad week moves it by more than a point. Treat the grade as a rough reading.
What to do with this
